4x4-Converted 1958 GMC 100 Pickup 4-Speed

Description

First introduced for the 1955 model year, GMC’s Task Force trucks were a significant evolution in light-duty pickups with modern styling, improved visibility, and increased comfort compared to their Advance Design predecessors. By ‘58, GMC had further refined the lineup with distinctive quad headlamp styling unique to the brand compared to their Chevy siblings, along with the introduction of the wider “Wideside” bed design, which offered a more integrated and contemporary appearance with added bed capacity.

This 1958 GMC 100 Pickup has been converted four-wheel drive with NAPCO-style two-speed transfer case reportedly sourced from a ‘50s-era Suburban. Power is provided by a 302 cubic-inch GMC inline-six engine, reportedly sourced from a light-duty commercial truck, paired with a four-speed synchromesh manual transmission.

Finished in Tartan Turquoise that has been ceramic coated, the truck sports a black vinyl bench with fabric inserts.

This modified 1958 GMC Pickup is now offered with removed parts and a clean Massachusetts title in the seller’s name.
